Abstract

The display apparatus includes a display panel having a display surface on one surface thereof, a back surface member disposed on the other surface side of the display panel, a light source disposed between the display panel and the back surface member, an outer frame body which covers a peripheral edge part of the display panel and surrounds the back surface member, and an inner frame body which holds the display panel and is provided in the outer frame body, wherein the inner frame body is made of a white color system synthetic resin containing light shielding characteristics. For example, the inner frame body contains a small amount of carbon black in a white color system polycarbonate resin.

Claims (38)

1. A display apparatus which includes a display panel having a display surface on one surface thereof, a back surface member disposed on the other surface side of the display panel, a light source disposed between the display panel and the back surface member, an outer frame body which covers a peripheral edge part of the display panel and surrounds the back surface member, and an inner frame body which holds the display panel and is provided in the outer frame body, the display apparatus further comprising:

a substrate with the light source disposed thereon; and

a heat dissipation plate with the substrate fixed,

wherein the inner frame body is made of a white color system synthetic resin containing light shielding characteristics, and

the outer frame body comprises:

a front face part covering the peripheral edge part of the display surface of the display panel, and

a side part which is bent from the front face part in a substantially L shape,

wherein the side part has a fitting hole, and

the inner frame body has a protrusion part to be fitted to the fitting hole, and the inner frame body is disposed between the heat dissipation plate and the side part.

2. The display apparatus according to claim 1 , comprising:

a light guide plate disposed between the display panel and the back surface member, wherein

the light source is disposed to face an end face of the light guide plate, and

the inner frame body is provided so as to shield light emitted by the light source from being made incident to the display panel.

3. The display apparatus according to claim 2 , wherein the inner frame body has a light shielding part disposed along the peripheral edge part of the display panel, between the display panel and the light guide plate.

4. The display apparatus according to claim 1 , wherein the inner frame body contains titanium oxide.

5. The display apparatus according to claim 1 , wherein the inner frame body has a reflectance of 45% or more.

6. A display apparatus which includes a display panel having a display surface on one surface thereof, a back surface member disposed on the other surface side of the display panel, a light source disposed between the display panel and the back surface member, an outer frame body which covers a peripheral edge part of the display panel and surrounds the back surface member, and an inner frame body which holds the display panel and is provided in the outer frame body,

wherein the inner frame body is made of a white color system synthetic resin containing light shielding characteristics, and

the inner frame body contains carbon black in a range of 0.003% to 0.02%.

7. A display apparatus which includes a display panel having a display surface on one surface thereof, a back surface member disposed on the other surface side of the display panel, a light source disposed between the display panel and the back surface member, an outer frame body which covers a peripheral edge part of the display panel and surrounds the back surface member, and an inner frame body which holds the display panel and is provided in the outer frame body,

wherein the inner frame body is made of a white color system synthetic resin containing light shielding characteristics, and

the inner frame body has a transmittance of light of 0.1% or less.

8. The display apparatus according to claim 2 , wherein the inner frame body comprises a side part chassis and a panel support part extending from the side part chassis toward the peripheral edge part of the display panel to support the display panel.

9. The display apparatus according to claim 8 , wherein the inner frame body comprises a light guide plate holding part extending from the panel support part toward the light guide plate to hold the light guide plate.

10. A display apparatus which includes a display panel having a display surface on one surface thereof, a back surface member disposed on the other surface side of the display panel, a light source disposed between the display panel and the back surface member, an outer frame body which covers a peripheral edge part of the display panel and surrounds the back surface member, and an inner frame body which holds the display panel and is provided in the outer frame body,

wherein the inner frame body is made of a white color system synthetic resin containing light shielding characteristics, and

the outer frame body comprises:

a front face part covering the peripheral edge part of the display surface of the display panel; and

a side part which is bent from the front face part in a substantially L shape, wherein the side part has a fitting hole, and

the inner frame body has a protrusion part to be fitted to the fitting hole, the display apparatus further comprising:

a light guide plate disposed between the display panel and the back surface member; and

optical sheets disposed between the display panel and the light guide plate,

wherein the light source is disposed to face an end face of the light guide plate, and

the inner frame body is provided so as to shield light emitted by the light source from being made incident to the display panel, and the inner frame body further comprises:

a side part chassis;

a panel support part extending from the side part chassis toward the peripheral edge part of the display panel to support the display panel;

a light guide plate holding part extending from the panel support part toward the light guide plate to hold the light guide plate; and

a sheet support part bent from the light guide plate holding part n a substantially L shape to support the optical sheets.
